Version 0.1.10

Backend changes:
* Added 3 columns to `enemy`, `weapon_dmg_min`, `weapon_dmg_max`, and `weapon_type`.  Fixes #52
* Created an Act method in Character class.  This will take care of incrementing actions and initiating logic between actions.
* Changed the following actions in Character class to call the new method: Wait, Move, Attack, PickupItem, EquipItem
* Removed IncrementAction method from Character class, since it is obsolete.
* Modified BeginGame to not increment actions when game starts.  It only increments `act_equip` once per item.  Fixes #36
